Record revenue: Net total revenue reached a record high of $155.0 million in Q1 2020 as compared to $73.3 in Q1 2019, an increase of approximately 112% primarily reflecting increased VASCEPA® (icosapent ethyl) prescription growth in the United States augmented by $6.7 million net product revenue from VASCEPA sales outside of the United States.

Commercial expansion: Increased size of U.S. sales force for VASCEPA in Q1 2020 to approximately 800 sales representatives plus their managers representing a doubling in size compared to most of 2019. All such new hires have now completed training and are interacting with healthcare providers, which interactions, commencing in mid-March, were transitioned to telephonic or other forms consistent with social distancing practices amidst the COVID-19 pandemic.

International progress: In Canada, Amarin’s commercial partner began promotion of VASCEPA in mid Q1 2020. As planned, Amarin’s commercial partner for Canada purchased VASCEPA capsules from Amarin to support their launch of VASCEPA. These purchases for Canada represented the majority of Amarin’s net product revenue from outside the United States in Q1 2020. In China, Amarin’s partner is nearing completion of their clinical trial of VASCEPA, the results of which are expected to be reported later this year based on our partner’s assumption of continued limited impact from COVID-19 on study completion. In Europe, the marketing authorization application for VASCEPA with the European Medicines Agency, or EMA, is undergoing review with an approval recommendation anticipated by Amarin near the end of 2020 and associated European Community, or EC, approval expected promptly thereafter, assuming continued limited impact of COVID-19 on the review. As previously disclosed, Amarin is taking a parallel path of evaluating whether it is best for long-term shareholder value to launch VASCEPA directly, in whole or in part, in Europe or to contract with a potential pan-European partner for VASCEPA promotion and sales. Amarin is targeting Q3 2020 for making this decision.

ANDA litigation update: As previously disclosed, Amarin and the defendants in the patent litigation pertaining to the initial indication for VASCEPA in the United States have agreed to expedite proceedings for the appeal of the district court decision. The parties have requested the U.S. Court of Appeals for the Federal Circuit approve an expedited schedule including requested briefing in Q2 2020 and an expedited hearing. This proposed timing should facilitate a hearing in Q3 2020 (or perhaps early Q4 2020) and position the court to rule thereafter potentially in 2020 or in early 2021. Amarin believes that it has a strong basis for appeal, which will be set out in its opening brief proposed for filing on May 12th.

“Amarin’s record revenue in Q1 2020 further confirms the value of VASCEPA’s new cardiovascular risk reduction indication and reflects that our commercial launch got off to a good start,” commented John Thero, Amarin’s president and chief executive officer. “We are regularly receiving positive responses from physicians about VASCEPA and witnessing further improvements in already good managed care coverage for VASCEPA supporting the large opportunity for this unique product. With strong science, great employees and wonderful collaborators, we are highly motivated to improve patient care for the millions of people worldwide who might benefit from VASCEPA while aggressively working to overcome challenges caused by COVID-19 restrictions and patent litigation.”

Commercialization Progress for Unique Drug

In mid-December 2019, the FDA approved VASCEPA as the first and only therapy for lowering persistent cardiovascular risk as studied in the landmark REDUCE-IT® cardiovascular outcomes study. Such approval reflects the results of over a decade of research and development which validated Amarin’s insights regarding the unique effects of the active ingredient in VASCEPA and the interaction of such effects on lipid management and cardiovascular health. This R&D program included three successful Phase 3 studies (MARINE, ANCHOR and REDUCE-IT). Amarin’s success over the development period faced many naysayers as multiple other companies and therapies fail to achieve similar results with other products.

The FDA approval of VASCEPA’s new cardiovascular risk indication allowed Amarin to launch VASCEPA in early 2020 with education and promotion to healthcare professionals. Review of educational and promotional messaging for patients has been undergoing separate FDA review. As previously communicated, Amarin intends to create a launch program for patient education and promotion in mid-2020. At the start of 2020, survey data supports that recognition and understanding of the unique effects of VASCEPA was relatively low among healthcare professionals and patients. This is not surprising as over the past decade Amarin spent the majority of its resources on research and development. VASCEPA promotion expanded in 2019. Acceleration of such promotion is a priority for 2020, including launch of VASCEPA’s new indication for cardiovascular risk reduction, the indication Amarin pursued for the past decade with the aim of helping millions of high-risk patients.

Regarding education and promotion of VASCEPA to healthcare professionals, in early 2019 Amarin increased the size of its direct sales force in the United States to approximately 400 sales representatives (plus their managers) representing an approximate doubling of the sales force size from the prior year. By Q3 2019, over 90% of the newly hired sales representatives were contributing positively (i.e., new contributions exceeded their cost). In early 2020, Amarin completed another round of expansion of its direct sales force in the United States. Amarin did so with the expectation that these new additions would contribute and more than cover their costs quickly. At the end of Q1 2020, Amarin had approximately 800 sales representatives (plus their managers). These new sales representatives were trained in waves which commenced in 2019 and accelerated in early 2020. It is too early to fully assess the performance of these newly hired sales representatives, but initial signs are encouraging although these expectations for new sales representative productivity in 2020 compared to 2019 are now tempered due to restrictions on in-person interactions pursuant to COVID-19.

The role of these sales representatives is to help educate healthcare professionals regarding how VASCEPA might be used to help their patients. During Q1 2020, we heard many positive anecdotes from the promotion of VASCEPA for cardiovascular risk reduction. The anecdotes came from prior prescribers and new prescribers of VASCEPA. We witnessed prescription growth among prior prescribers and new prescribers, including prescription growth in areas of the United States where we previously had no sales representation.

The sales growth in Q1 2020 was supported by broad managed care coverage across the United States. This coverage was good at the start of 2020 and improved during the quarter. Such improved managed care coverage reflects: 1) the FDA approval of a broad indication for VASCEPA (which approval did not include any special post-approval commitments reflecting the strength of VASCEPA’s robust and consistent clinical results); 2) ten esteemed medical societies that have already changed their guidelines to recommend icosapent ethyl (VASCEPA ) use or issued favorable statements for using our drug to care for at-risk patients; 3) multiple analyses presented in scientific forums showing that VASCEPA is highly cost effective with such analysis further suggesting that the preventative care solution demonstrated in REDUCE-IT holds the potential in most scenarios to save society money by preventing the high cost of cardiovascular events due to heart attacks, stroke, revascularization and death; and 4) the effective education of managed care providers and key opinion leaders regarding VASCEPA.

COVID-19 presents unique challenges for the launch of VASCEPA, particularly because many areas of the United States where reports of COVID-19 infection are most pronounced (e.g., metropolitan areas) are areas on which Amarin was relying for sales growth in 2020. During late March 2020, when Amarin suspended in-person sales calls due to COVID-19 social distancing priorities, we witnessed a decline in the rate of new prescriptions for VASCEPA. Our direct sales team has been finding new ways to interact with healthcare professionals and we continue to receive positive feedback from physicians regarding VASCEPA. However, many patients are not coming to physicians’ offices for routine visits due to risks of COVID-19 infection and the need for social distancing. While this environment may slow VASCEPA sales growth, we anticipate that most patients who currently take VASCEPA will continue to fill their prescriptions.

While we continue to experiment with new ways to interact with healthcare professionals during these challenging times, we are also preparing for the time when our sales team can begin to interact directly again with healthcare professionals. We believe that such interactions are important since VASCEPA has a new FDA-approved label and unique potential to help patients of which most healthcare professionals are not yet aware. Also, while VASCEPA has not been shown to reduce COVID-19 infections, patients at risk for cardiovascular disease appear to be at particularly high risk for COVID-19 related complications and we want to give healthcare professionals knowledge about VASCEPA which may be useful in lowering such cardiovascular risk in their patients.

Regarding education of consumers and patients about the cardioprotective effects of VASCEPA, we anticipate incorporating feedback from the FDA to potentially launch a patient-oriented campaign in mid-2020. Due to uncertainties stemming from COVID-19 and ANDA litigation, compared to what Amarin was planning at the start of 2020, Amarin currently intends to limit the extent of our patient-oriented campaign and focus primarily on education of and promotion to healthcare professionals. In particular, we intend to defer most or all of our planned television campaign because it is expensive and most of its value in providing education on the cardiovascular risk reduction effects of VASCEPA are likely not to be near-term. Such campaign will be readied for launch when and if we are successful in the appeal of the ANDA litigation assuming patients have resumed regular visits to their physicians by that time.

Prescription Growth in the U.S.

Based on monthly compilations of U.S. data provided by a third party, Symphony Health, the estimated number of normalized total VASCEPA prescriptions for the three months ended March 31, 2020 and 2019 was approximately 1,061,000 and 618,000, respectively, reflecting growth of 72%. According to data from another third party, IQVIA, the estimated number of normalized total VASCEPA prescriptions for the three months ended March 31, 2020 and 2019 was approximately 962,000 and 553,000, respectively, reflecting growth of 74%. Normalized total prescriptions represent the estimated total number of VASCEPA prescriptions dispensed to patients, calculated on a normalized basis (i.e., one month’s supply, or total capsules dispensed multiplied by the number of grams per capsule divided by 120 grams). Inventory levels at wholesalers tend to fluctuate based on seasonal factors, prescription trends and other factors; however, such inventory levels remained within normal industry range.

In Q1 2020, we saw prescription growth lag in January and February compared to trends in Q4 2019. We believe that such lag, similar to prior years, was due to high beginning of the year insurance deductibles as are increasingly prevalent in managed care coverage. Such deductibles are not product specific but do, as previously reported, impact whether patients can afford to fill prescriptions for all drugs at the beginning of the year. Historically this has led to prescriptions of drugs for asymptomatic chronic conditions such as cardiovascular disease not being filled. Throughout March 2020, prescription levels and related shipments of product increased over levels experienced in the first two months of Q1 2020 likely reflecting that some patients had overcome their insurance deductibles and that healthcare professionals were writing more prescriptions for VASCEPA and urging their high-risk patients to fill their VASCEPA prescriptions.

As described more fully in Amarin’s Quarterly Report on Form 10-Q, Amarin recognizes product revenue when its customers, consisting mostly of independent commercial distributors in the U.S., take possession of the product which they order from Amarin and Amarin ships to these customers. Amarin revenue is not recognized when individual patients fill prescriptions.

Shipments to the largest of Amarin’s customers, large wholesalers, tend to occur at the beginning of each week. The timing of the weekly calendar for Q1 2020 was such that shipments made to customers on Monday, March 30, 2020 were received by certain customers on March 31, 2020. As a result, for these customers there was effectively an added week of revenue shipments in Q1 2020 that did not exist in Q1 2019 when March 30th was on a weekend. While both reported revenue levels and reported prescription levels grew significantly in Q1 2020, this added week of shipments to certain customers, together with shipments of product to Canada (which don’t show up in data from Symphony Health or IQVIA) combined with a modest increase in VASCEPA’s net selling price (after rebates to managed care and other customary adjustments) in Q1 2020 explain the majority of the greater rate of increase in net product revenue reported for Q1 2020 compared to the rate of increase in prescription levels. Overall, inventory levels reported by wholesalers were within the normal industry range at the end of Q1 2020.

Further, as described previously, both Symphony Health and IQVIA collect and report estimates of prescription information. There is a limited amount of information available to such companies to determine the actual number of total prescriptions for prescription products like VASCEPA during such periods. Data reported by Symphony Health and IQVIA is rarely identical. Their estimates are based on a combination of data received from pharmacies that report such data and other distributors, and historical data when actual data is unavailable. Their calculations of changes in prescription levels between periods can be significantly affected by lags in data reporting from various sources or by changes in how pharmacies and other distributors provide data. Such methods can from time to time result in significant inaccuracies in information when ultimately compared with actual results. These inaccuracies have historically been most prevalent and pronounced during periods of time of inflections upward or downward in rates of use and less prevalent and pronounced over longer periods of time such as annually. As such, the resulting conclusions from such sources should be viewed with caution. Amarin cites such third-party information as a courtesy to its investors and because Amarin does not have direct access to prescription information. The prescription levels and changes in prescription levels reported above are based on information made available to Amarin from third-party resources and may be subject to adjustment and may overstate or understate actual prescriptions.

International Update

Amarin has expanded VASCEPA commercialization activities outside of the United States through several contractual arrangements in territories including China, the Middle East, North Africa and Canada. Amarin continues to assess other opportunities to develop VASCEPA commercialization outside of the United States through similar arrangements.

Amarin’s partner in China is conducting a clinical trial for VASCEPA which should report results later this year. Amarin has been informed by its partner that COVID-19 is not expected to have a significant impact on the clinical trial results in China or on the timing of such results. Assuming clinical trial success, this will position VASCEPA to be first in class in China.

Amarin continues to pursue a parallel process in Europe of evaluating whether to launch VASCEPA by itself in select countries, and partner other countries, or to enter into a pan-European partnership for the launch of VASCEPA. As previously reported, in Q4 2019 our regulatory submission for VASCEPA in Europe was accepted for review by the EMA. While we anticipate some impact on this review due to COVID-19, we do not expect this impact to shift the likely timing of the anticipated EMA recommendation for approval of VASCEPA in Europe from our estimate of near the end of 2020 and associated EC approval expected promptly thereafter. We seek a cardiovascular risk reduction indication in Europe.

In late 2019, Health Canada awarded approval, and in early 2020 granted extended regulatory exclusivity, to Amarin’s partner in Canada to market VASCEPA. Sales of VASCEPA have begun in the Canadian market.

Financial Update

Net product revenue for the three months ended March 31, 2020 and 2019 was approximately $152.2 million and $72.7 million, respectively. This $79.5 million increase in net product revenue was driven primarily by increased volume of sales for VASCEPA in the United States, which includes an additional week of revenue in the first quarter of 2020 of $10.8 million due to timing of orders placed by customers and related receipt, as well as a modest increase in VASCEPA’s net selling price reflecting various factors including managed care coverage improvements. In addition, the increase was also driven by VASCEPA sales outside of the United States of approximately $6.7 million during the three months ended March 31, 2020 as compared to $0.3 million during the three months ended March 31, 2019 primarily to ensure adequate product supply for Amarin’s commercial partner’s launch of VASCEPA in Canada (recognized upon shipment by Amarin to that partner).

In addition, Amarin recognized licensing and royalty revenue of approximately $2.8 million and $0.5 million for the three months ended March 31, 2020 and 2019, respectively, under agreements for the commercialization of VASCEPA outside the U.S.

Cost of goods sold for the three months ended March 31, 2020 and 2019 was $34.8 million and $17.1 million, respectively. Amarin’s overall gross margin on net product revenue was 77% and 76% for the three months ended March 31, 2020 and 2019, respectively. This increase in gross margin on product sales is driven by gross margin on U.S. product sales of 80%, partially offset by the gross margin on product sales to our partners outside the U.S. as per contractual arrangements. Net product revenue to our partners does not include licensing and royalty revenue.

Selling, general and administrative (SG&A) expenses during the three months ended March 31, 2020 and 2019 were $133.9 million and $71.6 million, respectively. This increase is due primarily to increased personnel costs related to the sales force expansion and an increase in promotional activities and direct to consumer promotion following the launch of VASCEPA in early 2020 for the new indication and expanded label approved by FDA.

Research and development expenses during the three months ended March 31, 2020 and 2019 were $10.3 million and $7.2 million, respectively. The increase in expense was primarily driven by costs beyond the conduct of the REDUCE-IT study to further analyze samples collected from REDUCE-IT patients as well as costs associated with the achievement of certain milestones under our strategic collaboration agreement with Mochida.

Under U.S. GAAP, Amarin reported a net loss of $20.6 million in the first quarter of 2020, or basic and diluted loss per share of $0.06. This net loss included $10.6 million in non-cash stock-based compensation expense. Amarin reported a net loss of $24.4 million in the first quarter of 2019, or basic and diluted loss per share of $0.07. This net loss included $6.9 million in non-cash stock-based compensation expense.

Excluding non-cash gains or losses for stock-based compensation, non-GAAP adjusted net loss was $10.0 million for the first quarter of 2020, or non-GAAP adjusted basic and diluted loss per share of $0.03, compared to non-GAAP adjusted net loss of $17.5 million for the first quarter of 2019, or non-GAAP adjusted basic and diluted loss per share of $0.05.

As of March 31, 2020, Amarin reported aggregate cash and investments of $623.7 million, consisting of cash and cash equivalents of $329.0 million and liquid short-term investments and long-term investments of $213.2 and $81.5 million, respectively. Net cash flow from operations was positive in Q1 2020 of approximately $4.1 million despite increases, as expected, in net accounts receivable, all of which were then current, reflecting revenue growth and inventory in preparation for anticipated future growth. As of March 31, 2020, Amarin reported $158.3 million in net accounts receivable ($189.6 million in gross accounts receivable before allowances and reserves), and $92.1 million in inventory. While, as previously expressed, until uncertainties regarding the effects and duration of COVID-19 and patent litigation are better understood Amarin is not providing an estimate of expected 2020 revenue results, based on its current plans and expectations, Amarin believes that its current capital resources are sufficient to achieve sustained positive cash flows from VASCEPA although results are anticipated to vary significantly on a quarterly basis including some potential negative net cash flow periods as Amarin works to launch VASCEPA based on its new cardiovascular risk reduction indication and adjust for various scenarios regarding the impacts of COVID-19 and potential launch of generic versions of VASCEPA in the United States.

As of March 31, 2020, Amarin had approximately 361.7 million American Depository Shares (ADSs) and ordinary shares outstanding, 28.9 million common share equivalents of Series A Convertible Preferred Shares outstanding and approximately 17.2 million equivalent shares underlying stock options at a weighted-average exercise price of $7.92, as well as 7.0 million equivalent shares underlying restricted or deferred stock units.

In light of logistics and financial difficulties created on some companies by COVID-19, Amarin recently completed a review of its supply chain to ensure continued supply and of its largest customers to ensure creditworthiness. We are pleased with the findings of this review. Regarding supply, the steps that we have taken to geographically diversify our supply chain together with steps we took to bolster inventory levels gives us confidence that we have adequate VASCEPA supply to meet anticipated demand for the foreseeable future. Regarding customers, we have little concern about our large wholesaler customers being able to continue to pay Amarin as and when amounts are due. As is done in the ordinary course, Amarin intends to periodically conduct such reviews and address new concerns, if any, as they arise.

Patent Litigation

As previously reported, the trial for the ANDA patent litigation against defendants Dr. Reddy’s Laboratories, Hikma Pharmaceuticals USA Inc. and certain of their respective affiliates, or the Defendants, took place in January 2020. On March 30, 2020, the Court issued its ruling in favor of the Defendants. Amarin is appealing the decision and may pursue additional remedies, including seeking a preliminary injunction against a generic product launch. If the generic version of VASCEPA proposed by either Defendant is approved by the FDA and the sponsor has qualified supply available and elects to launch at risk during the appeal process, such a launch would be at risk of damages such as lost profits to us should we prevail on appeal.

We intend to vigorously pursue appeal of the district court decision and plan robust increased product education and promotion if we win the appeal and plan various strategies for seeking to profit if the appeal is unsuccessful.

The results of this litigation do not apply to Canada, China, Europe or other international jurisdictions that don’t rely on determinations in United States courts. Furthermore, the label being sought for VASCEPA in many of these geographies are not for the triglyceride reduction indication at issue in this patient litigation in the United States. In addition, certain of the regulatory authorities in these geographies (e.g., Europe) provide added regulatory exclusivity that augments patent protection.

About Cardiovascular Risk

The number of deaths in the United States attributed to cardiovascular disease continues to rise.1,2 There are 605,000 new and 200,000 recurrent heart attacks per year (approximately 1 every 40 seconds), in the United States. Stroke rates are similar, accounting for 1 of every 19 U.S. deaths (approximately 1 every 40 seconds).3

Controlling bad cholesterol, also known as LDL-C, is one way to reduce a patient’s risk for cardiovascular events, such as heart attack, stroke or death. However, even with the achievement of target LDL-C levels, millions of patients still have significant and persistent risk of cardiovascular events, especially those patients with elevated triglycerides. Statin therapy has been shown to control LDL-C, thereby reducing the risk of cardiovascular events by 25-35% – but that still leaves a 65-75% risk remaining.4 People with elevated triglycerides have 35% more cardiovascular events compared to people with normal (in range) triglycerides taking statins.5,6,7

About VASCEPA® (icosapent ethyl) Capsules

VASCEPA (icosapent ethyl) capsules are the first-and-only prescription treatment approved by the FDA comprised solely of the active ingredient, icosapent ethyl (IPE), a unique form of eicosapentaenoic acid. VASCEPA was initially launched in the United States in 2013 based on the drug’s initial FDA approved indication for use as an adjunct therapy to diet to reduce triglyceride levels in adult patients with severe (≥500 mg/dL) hypertriglyceridemia. Since launch, VASCEPA has been prescribed over eight million times and is covered by most major medical insurance plans. The new, cardiovascular risk indication for VASCEPA was approved by the FDA in December 2019.

diabetes mellitus and two or more additional risk factors for cardiovascular disease.

As an adjunct to diet to reduce TG levels in adult patients with severe (≥ 500 mg/dL) hypertriglyceridemia.

The effect of VASCEPA on the risk for pancreatitis in patients with severe hypertriglyceridemia has not been determined.

Important Safety Information

VASCEPA is contraindicated in patients with known hypersensitivity (e.g., anaphylactic reaction) to VASCEPA or any of its components.

VASCEPA was associated with an increased risk (3% vs 2%) of atrial fibrillation or atrial flutter requiring hospitalization in a double-blind, placebo-controlled trial. The incidence of atrial fibrillation was greater in patients with a previous history of atrial fibrillation or atrial flutter.

It is not known whether patients with allergies to fish and/or shellfish are at an increased risk of an allergic reaction to VASCEPA. Patients with such allergies should discontinue VASCEPA if any reactions occur.

VASCEPA was associated with an increased risk (12% vs 10%) of bleeding in a double-blind, placebo-controlled trial. The incidence of bleeding was greater in patients receiving concomitant antithrombotic medications, such as aspirin, clopidogrel or warfarin.

This press release contains forward-looking statements, including expectations regarding financial metrics and performance such as prescription growth, revenue growth, operating expenses, inventory purchases, and managed care coverage for VASCEPA, including the impact of the COVID-19 pandemic, the outcome of patent litigation and the launch of generic competition on these metrics; the timing and outcome of regulatory reviews, recommendations and approvals in China, Europe and elsewhere; the timing and outcome of the clinical trial in China; the timing and outcome of the decision on whether to launch VASCEPA directly or with a partner on good terms in Europe; the timing and outcome of Amarin’s appeal of the patent litigation district court decision; the timing and status of promotion activities, including patient-oriented campaigns and education of healthcare professionals; commercial and international expansion, prescription growth and revenue growth and future revenue levels, including the contributions of recently hired sales representatives; the sufficiency of current capital resources to achieve sustained positive cash flows; ability of commercial supply; creditworthiness of its largest customers; expectations related to exclusivity in various jurisdictions and ongoing patent litigation appeal and associated business plans in various scenarios; and the impact of the COVID-19 pandemic on all of the forgoing. These forward-looking statements are not promises or guarantees and involve substantial risks and uncertainties. Amarin's ability to effectively commercialize VASCEPA will depend in part on its ability to continue to effectively finance its business, efforts of third parties, its ability to create market demand for VASCEPA through education, marketing and sales activities, to achieve broad market acceptance of VASCEPA, to receive adequate levels of reimbursement from third-party payers, to develop and maintain a consistent source of commercial supply at a competitive price, to comply with legal and regulatory requirements in connection with the sale and promotion of VASCEPA and to secure and maintain patent protection for VASCEPA. Among the factors that could cause actual results to differ materially from those described or projected herein include the following: uncertainties associated generally with research and development, clinical trials and related regulatory approvals; the risk that sales may not meet expectations and related cost may increase beyond expectations; the risk that patents may be determined to not be infringed or not be valid in patent litigation and applications may not result in issued patents sufficient to protect the VASCEPA franchise.
